Abstract: An object of the present invention is to provide the solar cell array improving the power generation amount per unit of setting area. According to the present invention, the solar cell panel, which is conventionally configured in a plane in the solar cell array, is provided in three dimensions, and the solar cell array which enables (1) the re-acceptance of the light reflected on the surface of one solar cell panel by another section of the solar cell panel and (2) the acceptance of the sky solar radiation in larger amount effectively by enlarging the area of the acceptance surface per unit of setting area so that the power generation amount per unit of setting area of the solar cell array may be increased is provided.
